Query string to Json in asp

[Katsumi]

i'm a beginner in ASP.Net and this is my first question in stackoverflow... i need to transform a query string, with a random number of parameters in json:\[code\]param1=hi&param2=hello&param3=byebye.... paramN=gudnight\[/code\]in something like this:\[code\]{"param1":"hi","param2":"hello","param3":"byebye"...,"paramN":"gudnight"}\[/code\]is there something to do this automatically in asp??
